with

the input element 36 of the prohibition of block 6, stopping the flow of clock pulses from the output of the generator 35 (to the input of the generator 37 and the input of the shift register 9 of block 1.

From each group of outputs (the group includes four outputs) of register 9 to the inputs of the corresponding converters 10 | - 10b code code (PC.K) is given the code 2421, which is converted to GAC in the output section-segment code N. Simultaneously from the output

The device works as follows.

Before the start of operation, the switches 54 and 55 of the block 8 are set, for example, in the ninth and first position, which, with a capacity of 47 and 48 counters equal to ten, ensures that the probability of the correct answer is set to 9.

Turn on the power. The registers 9, 14, 34, 38, counters 28, 47 and 48 are set to the initial state, and the trigger 13 is set to the position corresponding to "O at the forward output." By pressing the key 19, the unit is entered into the reversing register 14 of block 3 and advanced along register bits 14 by pressing the key 20, set to a position corresponding to the number of initially presented symbolic one-shot}, causing the appearance of a 50 ms pulse at its output. This pulse is applied to the control inputs of the indicators 11, ensuring that they are displayed for 50 ms.

The subject, fixing the visually presented numbers and their sequence in a row, reproduces the numbers in the same sequence by pressing the corresponding numeric keys of the keyboard 21 of the remote control 4.

For example, if the line shows the sequence 4 3 2 8 6 9, then the subject presses the first keyboard key 21, corresponding to digit 4. From the output of this key, the pulse arrives at the input of the encoder 22, ensuring that a four-digit binary code corresponding to the digit appears at its output 4 in code 2421 and identical to the code at the input of converter 10: block 1. From the output of the encoder 22 of the console 4, the code combination is fed through disjunctors 23 to the first to fourth information inputs of register 34 (second group input of block 5).

In addition, the pulse output from the key

For 35 with digit 4 through disjunctor 24 of console 4, it is fed to the first control input of register 34 of block 5, ensuring that the latter is switched to parallel recording mode, and to the input of delay element 26. From the output of element 26, a pulse is fed to the second control input of register 34, which ensures parallel recording of the binary number from the outputs of the remote controls 23 of the console 4 to the register 34. The pulse from the output of element 26 also goes to the first input of the single-generator generator 35 of the block 6 by pressing the "Start keyboard" button. 21 of the remote control unit 4. From the generator output 35, clock pulses through the prohibition element 36, to the control input of which zero potential is supplied from the output of the disjunctor 16 of block 3, the generator 37 is fed to the input, which provides the output at its output evdosluchaynoy pulse sequence which is applied to the first (informa40

The input) of the register 9 of block 1 and the recorder 27, causing the appearance at its output in register 9 with the help of clock pulses received at the second (shift) input of register 9 from the generator 35. From the third output of block 6 (generator output 35), the clock pulses (at the moment of arrival of a clock pulse at its clock input) arrive at a single potential in the form of a pulse of 4 T duration - four periods: a clock pulse. From the one-output output to the first input of the conjunctor 33 and the second 50 Pa 2, the unit potential is fed to the second input (synchronizing) of the single-oscillator 27 and the input of the conjunctor 33, which ensured block 5, but did not go any further, since The other inputs of these elements are given by the ow from the output of the generator 35 through the first zero potentials. In register 9 of block 1 of the input of conjunctor 33 to the third (recording continues to shift to occurring on the neck) input of register 34, and moving the separate input (between groups) 55 of the formation in register 34 to four cycles, four times, the second entry, i.e. its advancement into register 38 of block 7, in

The subject, fixing the visually presented numbers and their sequence in a row, reproduces the numbers in the same sequence by pressing the corresponding 0 numeric keys of the keyboard 21 of the remote control 4.

For example, if the line shows the sequence 4 3 2 8 6 9, then the subject presses the first keyboard key 21, corresponding to digit 4. From the output of this key, the pulse arrives at the input of the encoder 22, ensuring that a four-digit binary code corresponding to the digit appears at its output 4 in code 2421 and identical to the code at the input of converter 10: block 1. From the output of the encoder 22 of the console 4, the code combination is fed through disjunctors 23 to the first to fourth information inputs of register 34 (second group input of block 5).

In addition, the pulse output from the key
